Why this bike wins here

Legends and Lava is hilly, with 14.4 m of climbing per kilometre, the kind of course where aerodynamics usually counts for a little more than low weight. The Specialized S-Works Tarmac SL9 is an all-round frame, the kind of frame that terrain favours. Disc or regular wheels is a close call: the Cadex 4-Spoke/Disc is 2.5 s faster than the SwissSide HADRON Ultimate 650, but 0.37 kg heavier.

What the terrain rewards, from its climbing alone: aerodynamics against low weight

Extra watts are what the fastest setup needs to hold its pace on each surface rather than on tarmac, averaged over the ride - they appear once a ranked setup and mapped surface positions are there to simulate .
